part_channel

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must carry the full burden. It does not disclose side effects (e.g., nightbot being disconnected from all channel activity), authentication requirements, or the purpose of the 'dry_run' parameter. The action is described as disruptive but with no further detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence, but it sacrifices essential information about parameters and behavior. It is under-specified for an agent to reliably use.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 1 parameter with no documentation and no output schema, the description is incomplete. It does not explain return values, error conditions, or the effect of 'dry_run'. The agent lacks context to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage for parameters. The tool description does not mention the 'dry_run' parameter or its effect, leaving the agent unable to understand what it does.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Make Nightbot leave') and resource ('channel's chat'), differentiating it from sibling 'join_channel'. However, it lacks specificity about what 'leave the channel's chat' entails (e.g., does it disconnect Nightbot entirely?).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives (e.g., toggling default commands or sending a message). No prerequisites or context are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
